4

Could you clarify what you want with "4"? Do you want: - four exam-prep tips, or - four practice problems, or - help with problem #4 from a set? If you’d like a quick start right now, here are four universal exam-prep tips you can use immediately: 1) Map the syllabus: list all topics, note weights, and identify common question types. Plan a 4-week study schedule around this. 2) Practice actively: use active recall and spaced repetition (flashcards, self-quizzing) rather than passive rereading. 3) Do past papers under timed conditions: simulate exam environment to build familiarity and pacing. 4) Review and consolidate: analyze errors, form a concise formula sheet or crib sheet, and memorize key definitions, theorems, and steps.
